To a?! whom it may concern: v

lie it known that 1, EMIL l mnscnnn, a

subject of the (lei-man .Einperor, and resident ot.-'liergartenstrasse 252, Dresden-Altstadt, Saxony. Germany. have invented new and useful .ipparatus for Prodiwing Hot Producer-(ins, of which the following iSlL In specification of it, Patent No. 1041058 a process is described of manufacturin c a hot producer gas of over 1000 C.

by distilling non-bituminous-i'uels such as coke. anthracite or charcoal.

The present invention relates to an apparatus for manui'acturing such hot gas from bituminous l'uels. The new apparatus is also suitable for obtaining hy-products of coal such as tar, or'annnonia, and at the same time a mixed gas of high calorific 'value.

As explained in the priorspecification, the manufacture of hot gas is etleeted merely by the fuel wlneh enters the zone lrom wlnch the hot "as esca ieshein alread Y heated r- 7 H i practically to the temperature of the hot gas. This preliminary heating 1n the process :l'or manul'aeluring hot gas from non-. bituminous fuels. s ellected by a small por' tion (about 10%) of the hot gas which passes through the upper column of fueland escapes as a relatively coldgas. V

The same process obviously could be used even in the case of fuels which are only slightly bituminous such as anthracite coals. For ordinary bituminous coals, .howevcr, vit

would be necessary to lead for the purpose a very considerable quantity of gas through the upper layers of coal in order to effect distillation and also to heat the coke produced to the hot gas temperature. For the distillation ol? 1 lcg. coal alone rcuuires'a quantity of heat of in round figures '-l00 calories. It' therefore bituminous coal werc'to he treated in exactly the same way as coke or anthrm-vite, it would he impossible to ohtaiu any good yield olhot gas. Moreover, the volatile products of the coal such as tar, ammonia, or lighting gas would he so strongly diluted owing to the large eon-v sumption 01" hot gas for distillation, that it would be impossible to rely on an economic production ol these hyprodiu-ts or to expect a mixed gas of high calorific valve. There fore it was necessary to adopta new method in order to accomplish the above mentioned objects.

which the hot gas escapes, they must he prac-. 4

tirally completely edited. in order, however, to nsure that result, it 1s necessary-to form above the zone .troin which the hot gas escapes, a separate fuel layer which receives from ahove-na1nely the distilling charm berfalmost completely colteti coal, and d6- livers helow highly heated coke to the hot gas none. In that way the conditions for! ohtaining hot gas are complied with, audits niai'iuiacture is insured.

. "Ill In order to insure good preliminary heating of the separated 'fuellayer, a small quanv tity of hot gas entering, from below'passes through the said layer, but is burnt by means of secondary air blown in, before it escapes from this preliminary heating/compartment.

In that way heat is supplied to the fuel in" the said preliminary heating compartment,

both from below and from above Thehot gases pass from the preliminary heating compartment directly into the coal distilling eonn'mrtnient situated above, andefiects distillation' of the coal the hot gas manufacture are complied with, and at the same time only a small portion of the hot gas need he sacrificed for distilling contained" therein. I Thus,on the one hand, all: the conditions for a the coal. Of course, the coal distilling com;

partment could he still further subdivided, and the distillation also facilitated by supplying combustion air to these compartments. But this step would dilute the Waste gases. and thus render the manufacture of byproducts of the coals much more d fficult,

so that/it is more rational to introduce secs ondary aironly once. Qn the contrary, it

is :ulrantageous to mix steam with this 580- ondary air, which facilitates distiilation of the coals without any dilution of thewvaste gas being; produced; thereby (as steam is precipitated ii -the condenser).

Ordinary producers are not suitable for carrying out the process, but the producer must he built in accordance with the following. rinciples and as shown in the ac companying drawing which is'a longitudt nal. section through an apparatus of 'my present inyention. i

As will be seen fromthe drawing, the produeor is divided into three sections, that-is to say three compartments connected together.
